The purpose of this experimental study was to determine the effects of
vertical and horizontal models of plyometric training explosive strength
development in cadet volleyball cadets. Forty -four participants were
randomly assigned to one of two experimental groups: vertical
plyometric (Е1; n=20; BH=185.5 ± 7.02 cm; BM=71.1 ± 7.44 kg),
horizontal plyometric (Е2; n=24; BH=183.8 ± 7.79 cm; BM=68.7 ±
8.69 kg). The training programs lasted 6 weeks and it consisted of two
training sessions per week. All subjects were tested for each of the
following jumps: squat jump (SJ), countermovement jump (CMJ), drop
jump (DJ) and continous jumps (CJ). After a 6-week plyometric
training some of the tested parameters of SJ increased in the vertical
plyometrics group (Hmax 13.7%; Fmax 3.4%; Vmax 6.2%; IMPcon 4.1%;
Pmax_con 10.2%), as well as in the horizontal plyometrics group
(Hmax12.2%; Fmax 5.1%; Fmax/TT 6.0%; Vmax 5.9%; IMPcon 3.7%;
Pmax_con 9.5%). Some of the tested parameters of CMJ i...ncreased in the
vertical plyometrics group (Hmax 9.8%; Vmax 1.5%; IMPcon 7.2%;
IMPuk 2.0%; Pmax_con 2,8%), as well as in the horizontal plyometric
group (Hmax 10.1%; Vmax 3.4%; IMPcon 8.5%; IMPuk 5.0%; Pmax_con
3.9%), while lower values compared to the initial measurement were
recorded in Fmax/TМ (5.2%) in the vertical plyometric group. In DJ
some of the tested parameters increased in the vertical plyometric
group (Hmax 15.7%; Tcon 14.9%; Vmax 9.9%; IMPcon 14.4%; Pmax_con
10.4%), as well as in the horizontal plyometrics group (Hmax 23.4%;
Vmax 10.6%; Pmax_con 11.9%), while lower values compared to the initial
measurement were recorded in parameter Pmax_exc (13.3%) in horizontal
plyometric group. The CJ parameters showed in the vertical
plyometrics group increased (Hmax 8.2%; IMPuk 6.8%; Pmax_uk 4.8%), as
well as in the horizontal plyometrics group (Hmax 14.5%; Texc 6.0%;
IMPexc 12.2%; IMPuk 7.5%; Pmax_exc 13.8; Pmax_uk 6.2%). The results of
this thesis showed that there were no significant differences in the
effects of different models of plyometric program in tested parameters,
except for CMJ, in favor of horizontal plyometric group. The results
suggest that both training programs were effective in the development
of various parameters of jumping ability. In practice exercises from
these plyometric training program should be combined due to a greater
effect on certain parameters of jumps.
